This world has mermaids, you are a mermaid in this world, while you were swimming around the coral reef you saw a shiny light from the surface.

It got your attention so you swam up the surface, when you were sitting on a rock your eyes and mouth were covered, making you pass out.

When you woke up you notice that your tail was gone, it was replaced with legs.

You then notice someone at the door leaning against the wall grinning widely he then said, "Well hello there my little mermaid~".
